Period 9 Describing and Measuring Motion/ Acceleration Motion Speed For an object to be in motion, the distance from another object needs to be changing. Reference Point What you look at to see if you are in motion. You measure the speed by the distance the object travels per minute. Average Speed To find average speed you divide the total distance by the total time. Total Distance= 34km + 16km = 50km

Total Time= 2h + 8h =10 h

Average Speed= 50km/10h = 5km/h Instantaneous Speed The rate an object is moving at any given time.

The difference between average speed and instantaneous speed, is the average speed is the total distance traveled. Instantaneous speed is how fast an objects moving at any time. Velocity Velocity is how fast an object is moving in any direction.

The difference between speed and velocity is,

speed tells you how fast an object is moving, and velocity tells you how fast an object is moving in any direction. Acceleration How fast the velocity of an object changes.

* When an objects speed increases, the object accelerates

* When an object slows down when it comes to a stop

* An object accelerates when it changes direction Formula of Acceleration Acceleration= Final speed - Initial speed

time

Acceleration= 30m/s - 5m/s

5s

Acceleration= 5m/s2 Slope Slope is the steepness of a line.

Slope= Rise
